摘　　要：两竹地区铌矿矿石性质复杂,即使同在蒋家堰—天宝铌钽成矿带,其不同矿区矿点的矿石性质都不尽相同,主要含铌矿石类型以及矿石可选性都各有区别。本文分别对蒋家堰、天宝、野虎以及岩屋沟—青岩沟矿区的四个不同铌矿矿石性质和矿石可选性进行总结,结果表明,该区矿石普遍属于难选矿石,蒋家堰及岩屋沟K120样品的可选性要优于其他样品,矿石矿物嵌布粒度和分散量是影响其选矿指标的重要因素。The niobium ore in Liangzhu area is complex in nature.Even in the same Jiangjiayan-Tianbao niobium and tantalum ore-forming belt,the ore properties in different mining areas are not the same,and the main niobium containing ore types and ore selectivity are different.This paper summarizes the ore properties and ore selectivity of four different niobium ores in Jiangjiayan,Tianbao,Yehu and Yanwugou-Qingyangou mining areas respectively.The results show that the ore in this area is generally refractory one,and the selectivity of the samples of Jiangjiayan and Yanwugou K120 is better than that of other samples.The particle size and dispersion of mineral mosaic are the important factors that affect the mineral processing index.
